Why This Matters Across Episodes
The longer arc this connection carries
The cooling chamber escape sequence in Part 3 directly enables the shaft climbing sequence in Part 4, creating a causal chain where the Doctor's tactical innovation (using the ventilator shaft) leads to both peril (Dalek pursuit via anti-grav platform) and survival. This carries forward the Thal Resistance's strategic fight against the Daleks.

A directly causes B. The first event sets forces in motion that produce the second. These are the load-bearing connections of plot--remove one and the story structure collapses.
